NASA's CloudSat satellite sees a powerful heat engine in Typhoon Malakas

27.09.2010
Towering thunderstorms and heavy rainfall are two things that NASA's CloudSat satellite saw as it passed over Typhoon Malakas, and those two factors confirm a strong storm. NASA's CloudSat satellite's Cloud Profiling Radar can basically slice a tropical cyclone in half and take a look at its clouds and rainfall, and that's what it did when it passed over Typhoon Malakas on Sept. 23.

CloudSat flew over Typhoon Malakas during the daytime on Sept. 23. At that time, Malakas had a minimum central pressure of 965 millibars, maximum winds of around 115 mph (100 knots), and a storm width (winds greater than or equal to 57 mph or 50 knots) of around 150 nautical miles.


CloudSat captured an image of Typhoon Malakas at12:09 a.m. EDT on Sept. 23 that indicated strong convection on either side of the storm eyewall, with maximum cloud top heights around 9.3 miles (15 kilometers) in the southern quadrant of the storm, and approaching 10 miles (16 km) in the northern quadrant.

Dr. Matt Rogers, a research scientist who works on the CloudSat team at the Dept. of Atmospheric Science, Colorado State University, Fort Collins, Colo. noted that the " CloudSat overpass of the typhoon occurred around 4:09 GMT (12:09 a.m. EDT/1:09 p.m. local time/Japan), and radar imagery of the typhoon indicated strong convection on either side of the storm eyewall, with maximum cloud top heights around 9.3 miles (15 kilometers) in the southern quadrant of the storm, and approaching 10 miles (16 km) in the northern quadrant."

A strong convective (rapidly rising air that creates the thunderstorms that power a tropical cyclone) cell dominates the northern quadrant of the storm, while several smaller convective cells combine to make up the southern quadrant, according to the CloudSat overpass.

"The presence of heavy rainfall near the storm core causes radar attenuation - a condition that occurs when the vast amount of water present in the storm scatters or absorbs all available radar energy, leaving no signal to return to the satellite," Rogers said.

Satellite data also detected an eye 50 nautical miles wide, and around it were the strong thunderstorms wrapping around it and into the storm's center from the southeastern quadrant.

At 1500 UTC (11 a.m. EDT) on Sept. 24, Typhoon Malakas has maximum sustained winds near 103 mph (90 knots). It was located about 75 nautical miles west-northwest of Chi Chi Jima, Japan near 29.8 North and 142.4 East. It was moving north-northeast near 26 mph (23 knots) and kicking up 31-foot high seas.

Malakas has tracked over Iwo To and Chi Chi Jima and is now headed into open waters this weekend. It is forecast to stay at sea and away from land, paralleling the coast of Japan. By Saturday, Malakas is forecast to start transitioning into an extra-tropical storm and weaken gradually. As it continues northeast it will encounter stronger vertical westerly wind shear which will help weaken the system somewhat, but it is forecast to still remain an intense storm after the transition.

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
